1. A production method for obtaining 1,1,1-trifluoro-2,2-bisarylethane, the method comprising subjecting an aryl compound represented by General

OG Complex Work Unit Chemistry
wherein, in General Formula [1], X1 each independently represents a hydroxyl group, an amino group, a carboxyl group, or a halogen, m represents an integer of 0 to 3, R1 each independently represents a monovalent organic group, and n represents an integer of 0 to (5-m),
to a condensation reaction with a mixture of fluoral and hydrogen fluoride under anhydrous conditions,
the 1,1,1-trifluoro-2,2-bisarylethane being represented by

OG Complex Work Unit Chemistry
wherein, in General Formula [2], X1, R1, m, and n each have the same definition as X1, R1, m, and n in General Formula [1].
